SPECIFICATION forming part of Letters Patent No. 288,421, dated November13, 1883.

Application llled September 11, 1883. (No model.)

I?) aZZ whom it may concern:

Be it known that I, LOUIS GODDU, of \Vinehester, county of Middlesex,State of Massachusetts, have invented an Improvement in NailingMachines,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention is an improvement on the IO machine represented in UnitedStates Patent No. 265,227, granted to me September 24, 1882, and towhich reference may be had.

My present invention comprehends improvements in the chutes whichconduct the nails or I 5 fastenings to the nose or nail tube, and meansto remove the same singly from the chute to be acted upon by the driveror driven into the stock.

In this present invention bevel-wheels lo- 2o cated near the end of eachroadway of the chute, and having teeth of suitable length, are employed,instead of the sliding bifurcated separators shown in the said patent,and with the said toothed wheels Ihave combined mechanism whereby eitherof them may be operated at will to receive and convey to the driver anail of the proper length. either of the said wheels being actuated atwill according to the length of nail or fastening which it is desired todrive. The spaces or teeth in the said wheels which receive the nails orfastenings are so shaped and proportioned with relation to the nail tobe fed by it to the driver that but one nail can enter one space.

Figure 1 is a detail showing part of the vi brating head which carriesthe usual driver and-awl-bars and the nail-receiving drum and chute,sufficient in connection with the said patent to illustrate my presentimprovements. Fig. 2 is a view on a larger scale of the top of thedouble roadway and rotating separators or wheels, the arms which carrythe pawl for actuating the said wheels being in section. Fig. 3 is asection of Fig. 1 in the irregular dotted line as m, but on an enlargedscale, to

illustrate the cam-shaft and devices for moving the pawl-carrying arm;Fig.4, a broken elevation from the right of Fig. 1, and Fig. 5

a detail showing the manner of holding the pawls in their arms.

In the drawings, the vibrating head 13, driver-bar a, the nail-receivingdrum E, the chute m, cover a, the stops f f", sector f tube fspring-pressed pin f throat c, and shaft 0 are all as in my patentreferred to, and derive mo- 5 5 tion as therein shown; so need not beherein further described.

The chute 1n has two roadways, 2 8, and the nails therein will becovered by the cover of. The lower end of the chute is joined with thethroat c by a bolt, 5. The throat has vertical passages 7 8 for theusual awl and driver, respectively.

Into the side of each roadway, at or near the lower end of the chute,where the roadways 5 are divided only by the narrow wall 9, I eX- tendthe teeth of the rotating separators or bevel-toothed wheels 10 12,mounted, respectivcly, .onpins 13 14, fast in the nose. These separatorshave the spaces between their teeth and the length and width of theteeth so proportioned with relation to the diameter or size of the nailsor fastenings 15 16, to be driven, that but one nail at a time can getinto one of the spaces of the separators. These separa- 7 tors are movedintermittingly one at a time and for any desired number of times insuccession by means of pawls, one for each separator.

The separator 12 is moved by a pawl, 17, connected with a lever or arm,18, having a solid or rigid pin extended through the head 13, and havingapplied to its other end an arm,

20, which is joined by a spring, 21, with alike arm, 22, on the rigidpin 23 of the arm 24, which carries the pawl 25, that turns theseparator or wheel 10. Each pawl is connected with its lever or arm by aspring, 26, the flanged and notched end of which enters a groove, 27, atthe upper end of the pawl, as shown best in Fig. 5, and,'asshown in thesaid figure, the said pawl is slabbed off, making a corner, 28, againstwhich the said spring bears, so that the point of thesaid pawl is bornetoward and so as to engage the teeth of 9 5 the said separator andcarrier, whichreceives from the roadway the nail to be driven andcarries it opposite and under the driver-passage 8, in which positionthe driver in its descent meets the head of the nail and drives it belowthe carrier into the stock below the usual nose, 0. In practice thespaces between the teeth of the rotary separators or carriers correspondsubstantially in shape and size with one-half of the driver-passage.

The shaft 0, common to the patent referred to, instead of being providedwith cams f, as in the said patent, is provided with two cams or disks,30 31, with their acting faces turned toward each other, as shown inFig. 3, and so that cam 30 will act against the roller stud or pin 32 ofarm 18, and the cam 31 against a like roller stud or pin, 33, on the arm24. Either of the arms 18 or 24 may be so held that the actuating-camcannot strike and move it, and one or the other of the said arms will beheld, according to which roadway is to supply the nails to be driven,for the nails taken from the roadway 3 are removed by the separator andcarrier 12, while those from the roadway 2 are removed by the separatorand car rier 10. If it is desired to lock out of action the arm 18, pawl17, and the separator 12, and enable the arm 24 to move the separatorand carrier 10, to take nails from the roadway 2, then the usual tube, fwill be turned in the proper direction to cause the stop f to act uponthe arm 18 and hold it back, so that the cam 30 cannot strike it. Suchmovement of the tube to enable the stop f to hold the on-111 18, drawsback the stop f and permits the spring 21 to hold the roller-stud 33 ofarm 24 against the cam 31, so that the said cam effects the movement ofthe pawl 25 backward over the teeth of the carrier 10, and when the saidpawl engages a new tooth the cam 31, by its change of position and owingto its shape, has reached such a point as to permit the spring 21 tobecome the mover for the arm 24 and pawl 25, the latter then turning thesepa rator and carrier 10 far enough to take a nail, 16, from theroadway 2 and carry it into position under the driver.

In practice the separator or carrier will be acted upon by a suitablefriction device to prevent them moving farther than they are positivelyto be moved by the pawls. The operator desiring a different length ofnail from that which the machine is then driving will turn the tubef andset it so that the change to bring the otherlength of nail intooperation will be effected automatically as soon as the cams 30 31arrive in the proper position to enable the stops to move and effect thechange desired automaticallyas, for instance, if the tube f is shiftedto force in the stop f 3 at the left of Fig. 1 at a time when the arm 18is directly in front of it, the said stop cannot get behind the said armto hold it until the cam 30 moves the said arm past its end. While thestop is waiting its chance to operate, as it may be said, the springwhich acts on the usual spring-pin, f is compressed.

Referring to Fig. 2, it will be seen that the narrow division-wall 9 ofthe chute between the two roadways comes to a taper, and the end ofthesaid wall is made to form part of the driver-passage, and the headsof the nails 15 and 16, the bodies of which are engaged by theseparators and carriers, rest upon and are supported by the said wall upto the driverpassage, and the opposite side of the head is supportedupon the moving separator, so the separator acts to carry the head alongon the said wall up to the driver-passage.

I claim 1. Ihe chute and two roadways, combined with two rotatingseparators provided with teeth which project into the said roadways, andwhich are adapted to carry nails from either of the said roadways atwill to the driver-passage, substantially as described.

2. The chute and a roadway therein for nails, and a rotating separatorhaving its teeth extended into the said roadway to separate and removethe nails, combined with a'pawl and arms to carry it, and means tooperate the said arm intermittingly, whereby the said separator is alsooperated intermittingly, substantially as described.

3. The chute and two roadways, and two rotating separators made astoothed wheels, and having their teeth extended into the said roadways,combined with two arms and pawls, either of whichmay be operated atwill, and the other held out of operation to enable either one of thetwo separators to present in the driverpassage nails from the roadwaywith which it co-operates, substantially as described.

4. The chute provided with two roadways and a division-wall tapered atits end next to and terminating at the driver-passage, combined with thetwo rotating separators, to operate substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
